Solve left|-3right|+1-sqrt{4}+tan(45^circ)

$$\left| -3 \right| +1- \sqrt{ 4 } + \tan ( 45 ^ { \circ } )$$

Evaluate

$$3$$

Solution Steps

The absolute value of a real number a is a when a\geq 0, or -a when a<0. The absolute value of -3 is 3.

$$3+1-\sqrt{4}+\tan(45)$$

Add 3 and 1 to get 4.

$$4-\sqrt{4}+\tan(45)$$

Calculate the square root of 4 and get 2.

$$4-2+\tan(45)$$

Subtract 2 from 4 to get 2.

$$2+\tan(45)$$

Get the value of \tan(45) from trigonometric values table.

$$2+1$$

Add 2 and 1 to get 3.

$$3$$
